How does the gears attach to the freehub
Hi Tony, The kit is the freehub body itself (plus the Ratchet EXP internals), and the cassette mounts onto it rather than the other way around. The freehub body has external splines; the cassette's sprockets have matching internal splines and slide straight on, with one wider spline that sets the orientation, then a lockring threads in to clamp the stack in place. This one takes a Shimano 11-speed road cassette. Many thanks
